It's a matter of crunching numbers, as others have suggested.
Do be aware that appliance efficiency may vary considerably with the fuel source. The fridge is probably pretty close to the same for propane vs. electric--it uses the same total energy from either one, more or less.
An electric space heater is about 100% efficient at converting electricity into heated air in the RV. A propane furnace is less so, maybe 70-75% or so for an RV furnace (a guess).
An electric water heater element is about 100% efficient at converting electricity into heated water (ignoring loss from the tank, which is the same regardless). The propane burner would be less efficient.
If you have to drive to get more propane, take that fuel into account unless you are pretty sure you'd already be driving that far for other reasons.
